Feingold, who was unseated in 2010 by now-Sen. Ron Johnson (R), launched his Progressives United PAC in February, with a keen focus on pushing back against the Supreme Court's Citizens United ruling that rejected limiting corporate political spending. Whatever may be in Feingold's political future, it's clear the dispute in Wisconsin allows the former senator to remain visible to his progressive base in a debate that has become increasingly political in recent weeks. And in a state without a deep Democratic bench, expect Feingold's name to continue to surface in discussions about future races. -- Reid Wilson contributed to this post.
